SS RBC fractions were separated by density on arabinogalactan gradients. Equal numbers of cells in each fraction were used in the flow adhesion assay. Denser, reticulocyte-depleted RBCs were approximately nine times more adhesive to hLAM than the least dense, reticulocyte-enriched fraction. Data from 4 patients are shown.
